<p>Method for the determination of the aerobic biodegradability in a composting device of at least one product, characterized in that an amount of the product is mixed with an amount of active inoculum and, if necessary, with an amount of water, such that the dry matter content of the mixture is situated between 40 and 60%, through at least one quantity of this mixture, that is maintained at a temperature of between 20 and 75 degrees Centigrade, gas containing oxygen is passed with a known CO2 content that is preferably zero, the amount of CO2 coming from the mixture is accurately measured or calculated, an amount of inoculum alone is treated in just the same manner with the gas containing oxygen and also moreover the amount of CO2 in the outflowing gas is measured, and finally on the basis of the amounts of CO2 the amount of carbon is determined which originates from the product alone and is converted into CO2 through biological activity. <IMAGE></p> |
